Compact Polarization Diversity Dielectric Resonator Antenna Array for WLAN Application

This paper presents the study on a compact polarization diversity antenna array consisting of two orthogonally placed hybrid dielectric resonator antenna (DRA) elements. A prototype antenna array for IEEE802.11a WLAN application is designed and measured. Over 20 dB isolation and 18% input impedance bandwidth is achieved while symmetrical and unidirectional radiation patterns are maintained over...

A Cylindrical Dielectric Resonator Antenna for Wireless Body Area Networks

In this paper, a hybrid dual-band cylindrical dielectric resonator antenna with parasitic slot fed by a microstrip line that is suitable for wireless body area network is proposed. In this configuration, the dielectric resonator performs the functions of an effective radiator along with the feeding structure and the slot in the ground plane. By optimizing the structural parameters, the antenna ...

A Compact Dual Band Dielectric Resonator Antenna For Wireless Applications

This paper presents the design of a dual band rectangular Dielectric Resonator Antenna (DRA) coupled to narrow slot aperture that is fed by microstrip line. The fundamental TE111 mode and higher-order TE113 mode are excited with their resonant frequencies respectively. These frequencies can be controlled by changing the DRA dimensions. A dielectric resonator with high permittivity is used to mi...
